Calcined and hydrated lime

Hydrated lime is the same as CaO live lime, which when combined with water turns into hydrated lime or dead lime or water lime. Its chemical name is calcium hydroxide.

Lime has a strong affinity for water. Calcium carbonate is a chemical compound and synthesis with the formula CaCO3. It has a chemical composition of calcium hydroxide, which is rarely found in the form of pure lime in nature. Slaked Lime is obtained by combining quicklime with water. Hydrated lime has the chemical formula Ca (OH) 2 and is a white powder and is one-handed. Hydrated lime is also called hydrated lime. It is unstable against air and humidity. In order to produce quicklime, limestone must be heated in horizontal kilns. Quicklime has a strong affinity for metals, so it is combined with metals used in the building, such as water pipes and boiler pipes. They corrode and cause decay. For this reason, the consumption of lime in the building has been gradually reduced and with the development of cement factories in Iran and around the world, cement has gradually replaced lime in the construction industry, so that today lime is used as a mortar in less buildings.
